Application filed July 19, 1919. Serial No. 311,929.

To all whom it may concern:

Be it known that I, PETER IIMACK,' a citizen of the United States, and resident of St. Louisandv State of Missouri, have invented certain new and useful Improvements in Movable Center Frogs, of which the following is a specification containing afull,

references, be-

clear, and exact description, ng had to accompanying drawings, formlng a part. thereof.

frogs, andflhas for its primary object a center frog with movable points whichare con-' nected together'by a lever mechanism, so

site directions simultaneously.

A further'object is to construct 'a movable center frog which may be operated either" from a tower, be hand thrown,-or operate automatically bythe passingof the wheels. v In the drawings; a

attached.

In the construction of my deviceI provide a housing 11, on which is integrally formed the raid 13, only partially from 'eachLend.

frog point 16 is seated. 'The frog point 16 is provided'with an upwardly-and rearwardly projecting flange i or Web 17 which is designed to come contact with the flange of acar wheel.

The point 16' is provided at its rear end This invention relates to movable center that the opposing points-willmove in oppo- View of my device as -Fig. 3 isga top plan view of'thelever" to the pins y and therefore will Fig. 10 is a perspective view of the yoke to 'which the lock bars and 'backthrow rods are the running rails '12'and'13, the rail 12*ex- .tendin thefull' length of thehousing, and cured to the The running rails 13 are further provided witha "socket 14 in which the'end15 of the l with a pivot or stud 18, this pivot or stud being formed on the underside of the point.

The housing 11 is provided on its underside with a series of ribs 19, these ribs beingperforated as indicated by the numeral 20.v j

The upper surface of the housing 11- is provided with an opening 21 which is formed directly above the opening 20 formed in the ribs 19 andthrough these two openings the pivot 18 is passed. 7 p

'The housing 11 is also provided with slotted openings 22 through which studs 23 pass. These studs are formed integral with the bottom side of the points 16 and at a short distance from the free end thereof;

*The centerofthe'housing 11 is provided with an opening '24 which-is directly over. an opening 25 formedin the rib 26, which rib is also formed integral with the bottom of the housing. Through these openings the pin-27 is secured. I 7 V v On this pin and under'the top surface of the housing 11 ispivotally secured a lever 28, this lever being provided on both of its ends with a fork 29, which fork straddles the pin 23. 1

Immediately below this lever and secured 23 and 18 is the barBO, this bar being 'prov'idedon each of its ends with a perforation 31. To theseperforations the f locking'ba-rs 32 and the back throw rods 34 aresecured. V

Secured to the pin neath the levers 30 are secured the head rods 35, and in order to keep the housing at the proper distance gage rods 36 are secured. These gagerods are of standard construction not'be described in detail as they are well known articles ofcommerce; The head rods 35 are riveted in the depression 37 f0rmedin the yoke'38 and oppo-' site the depression 37 is formed a perforated 1 car 39, this car being for the purpose of connecting the head rods directly to the switch stand, if so desired; Adjustably sehead rods are inter-locking bars 40, their connection is not shown as this is well-known to the art; The lock bar connection 32 is secured to the yoke 42. p This connection also is provided with an extension or rod 41 which may be-secured to the switch stand or target for operating the The lock bars 32 are provided a fork 44 and the nuts 44 which are for. the purpose of adjusting the points of the frogs. The rear end of the lever 30 isconnected to an adjustable rod 45 whichis provided with 5 a turn buckle 46 and is for the purpose of locking the frogs in adjusted position. In
